Figure 4 is a detail plan view partly in section;

showing a portion of the means for operatingth'e inkingmechanism as itappears in the direction of the arrow 4 of Figure-3.

" Referring to Figure 1 of the drawings: 11 indicates the base frame ofthe printing machine. Two printing units are shown and designatedrespectively A and B. The side frames of the printing units areindicated at 12. Similar side frames are used onthe opposite side ofthemachine, a portion of one of them being shown in Figure 3 andindicated as 12'. A folder of well known design is shown and' indicatedgenerally by the letterF.

v -The main. drivingnshaft 14 is provided with bevel gears 15 that meshwith similar. gears 16 on inclined shafts 17 and serve as a means todrive the printing units. Similarly, the mitre' gear 13 on the mainshaft, meshes with th g ar falignment with the impression cylinder 35ing machine, partly in diagrammaticform and thefolder.

19 on the shaft 21 and serves to drive the folding mechanism indicatedgenerally as F.

The printing units each include a first or lower printing couple and asecond or upper printing couple. The first printing couple has a formcylinder 34'and an impression cylinder 35, supported preferably inhorizontal alignment and-arranged to rotate in bearings carried in theframes 12 and 12.-

A first ink cylinder 36, a second ink cylinder 3'1, form rollers 38 and39, transferrollers 40 and 41 and distributing rollers 42, 43 and 4%,,are all likewise rotatably supported by bearings carried by the frames12 and 12C, The printing cylinders of the second printing couple are op-73) positely arranged, and are indicated at as" and 35.. r

The ink cylinders for the second couple are indicated at 36' and 37%form rollers at 38' and 39' and transfer rollers 40 and 41' and the dis-7% tributing rollers at 42, 43' and 44'. l It..wi1l be noted that-theform cylinder 34 is in vertical alignment with the impression cylinder35 and the form cylinder 34 is in vertical Ink supplying mechanism isshown herein in the form of a pump device which is well known in the artand which provides separate ducts,

each of which feeds ink to a. separate section of the inking cylinder.The ink supply mechanism for the first printing couple is. indicated atA5,

and that for the second printing couple at 45'.

The-side frames 12 and '12" support an upper frame, partially shown inthe drawings as 46,

whichcarrie's guide rollers, bearings and turner bars, in accordancewith usual practice to deliver the webs W and W to the folderF. r Webguide rollers are provided in the printing units at 4'1, 48, and'49 bymeans of which the webs W and W are led from suitable mechanism locatedon a level below the base frame oflthe printing machine to and throughthe printing units and thence around the guide rollers to j -Web feedingplates or guides 51 and 51' are 9 carried by suitable brackets. attachedto the frame of the machine and so arranged that when threading the endof the web through the machine, it may be placed on the feeding plates.5 and pushed forward into the bite of the printing cylinders, thussimplifying the operation of threadlngthe web and avoiding danger ofaccident to the operator. Thev arrangement of guides H of this kind isfully described in United States Patent No. 1,613,960 granted to L. A.Schmidt on January 1-1, 1927.

The unit drive shafts 17 are supported in bearings formed in bracketssecured to the side frame and indicated at 52, 589ml 54. The bevel gearindicated at 55 is secured to the shaft 17 and 67, the opposite ends ofwhich are secured in themeshes with a similar gear that'is connectedwith the impression cylinder 35. Similarly, the gear der of the unit onwhich the platform is mounted, and also to the lower form cylinder ofthe adjacent unit. The arrangement of the cylinders in the frame, issuch that the platform can be placed at a height not exceeding one stepand still provide convenient access to the adjacent printing cylinders.

The preferred inking mechanism is shown in greater detail in Figures 2and 3, and in addition to the parts previously described, includesmechanism for driving the ink'cylinders and moving or vibratingthem'axially.

The-impression cylinder 35 and the form cylinder 84 and likewise theimpression cylinder 35 and the form cylinder 34' are geared together inpairs in the usual manner, and the shaft of the form cylinder '34" isextended as indicated in Figure 3 at 59, and a gear 61 is secured to it,and

this is similarly true of the shaft of .the form cylinder 34.

This gear 61 meshes with an idler gear 62 rotatably supported on a stud63. The idler gear 62 meshes with a gear64 that is secured to the shaft65 of the inking cylinder 3'7. Similarly, an idler .gear66 is rotatablysupported on the stud 6-7 and meshes with the gear 64, and with a gear68 that is secured to'the shaft 69 of the ink cylinder 36. Means arethusprovided for rotating both ink cylinders in timed relation with theprinting cylinders.

A' gear housing and bracket indicated at 71, is

secured to the side frame 12' and is fitted with bearin gs at'severalpoints indicated by the numera1 72, which serve torota t'ably support acrank or vibrator shaft 73. The'member 71 also serves to support one endof each of the studs 63 and frame 9 12'. A -wormwheel 74 is secured tothe crank shaft '73 and meshes with a worm 75' secured to the. shaft 59of the cylinder 34. i

The crank shaft '73 is formed with cranks '16 an 76', one of these beingshown best in Figure 4,

and these cranks may also be made as eccentrics if desired. Connecting.rods or pitmen Ware secured to wrist pins '18 that rotate in holesformed in lugs 78' that extend from the caps 79. The'.

caps '19 are secured to swivel rings 81, which rotatably support theshafts 65 and 69. The as- 'semblage includingthe caps 79 andthe swivelrings 81 constitutes the preferred formof the mechanism hereinafterreferred to as a swivel member. I

It will be understoodthat a ball bearing indicated'at' 82 in Figure 4,serves asa thrust member and has its inner member secured to the shaft'65 by means of the nut 83 and the outer member of the ball bearingissecured in the swivel ring 81 by the cap 79, and this construction alsoapplies to the other ink rollershaft 69.

a The ball bearing which is of the deep groove type tion tothecooperating impression cylinders and is adapted to transmit axial thrustin either directiqn and the rotation of the crank or vibrator shaft 73will thus result in moving or vibrating the shafts 65 and 69 forward andbackward longitudinally in their bearings, while the inking cylinderswill simultaneously be rotated through the gear train hereinbeforedescribed.

Means for adjusting the impression contact between the form cylindersand the impression cylinders .is provided by eccentric bushings 84 and84 which form the bearings for the shafts of the form cylinders 34 and34'. Segments 85 and 85 are secured respectively-to bearing bushings 84and 84 and have teeth which'mesh with worms 8 6 and 86' having shafts 87and 87' rotatably :supported in brackets 88 and 88' secured to the sideframes 12 and 12'. It will be understood that by rotating theshafts 87and 87 that'their respective form cylinders will be moved with rela- 5 9may be adjusted to obtain 'the requisite printing pressure. Gylinderadjustment mechanism of this kind is fully described in United StatesPatent No. 1,824,436 granted to F. Lamatsch on Septem ber 22, 1931.

The arrangement of the printing couples and the inking mechanism, in theframes of the machine is such that the ink distributing cylinders arewithin the space bounded by vertical lines tangent to the peripheries oftheir respective form cylinders, and the axes of the cylinders of theupper printing couple are in substantially vertical alignment with theaxes of the printing cylin-'- tiers of the lower couple and separatedtherefrom a distance not exceeding the width of the nally move saidshaft, the shaft being rotatable relatively to the swivel member, acrank shaft operatably connected by the swivel-member, and means torotate the crank shaft.
